Bridges - Application Note

A SUCCESSFUL BRIDGE-MONITORING PROGRAM RE-QUIRES APPROPRIATE PLANNING, DESIGN AND EXECU-TION. TO FULLY MEET THE OBJECTIVES OF SUCH A PROGRAM, SPECIAL ATTENTION MUST BE GIVEN TO THE SPECIFICITIES OF EACH BRIDGE THROUGHOUT THIS PROCESS.

The primary function of monitoring is to ensure the longevity and safety of a bridge as well as optimizing its management. To implement corrective measures and maintenance actions, monitoring must enable the timely detection of any condition or behavior that could deteriorate the bridge, deem it unsafe or potentially result in its failure.

The monitoring program plays a fundamental role during the construction phase as it enables the verification of design hy-potheses and construction processes, affecting, in some cases, the construction rate of the bridge and its overall quality. Most defects are already introduced at the time of construction. Monitoring also allows performance evaluation of new materials

and technologies used in bridge construction and rehabilitation. This objective is easily achieved with fiber optic sensors, since these sensors effectively integrate in new materials such as fiber-reinforced polymer composite. Furthermore, fiber optic sensors adapt perfectly to long-term monitoring of bridges behavior as well as short-term monitoring of the bridges dynamic behavior under traffic load. Finally, monitoring can be used as a tool for the “supervised lifetime extension” of bridges approaching the end of their life or in need of major repair. It ensures that such bridges are operat-ed safely while allowing the postponement of major investments and traffic disruptions.
